You seriously think discipline in the Udmurtian army is comparable to Ukraine ?
I expect it is much better, actually.
Ukraine has maybe not a true "citizen army" (too many people of means have escaped), but its army still represents a wider cross section of Ukrainian society than the Russian army does of Russian society.
That is, Ukraine's army really does have plenty of lawyers, dentists, clerks, managers, etc.
Russia's army is mostly made up contract soldiers, conscripts that were rolled over, and mobilized reservists.
I'm not saying there aren't a large number of middle-aged Russians fumbling about on the front, but there's proportionately less of them than in Ukraine.
Want to know what happens when you send a 45 year old lawyer to the front, where a 25 year old commander will berate him before sending him on a suicidal mission? You get the same issues every corporate HR department has dealt with at some point. However, in military terms - what you get is a degradation of discipline.
Ukrainian units routinely refuse/disobey commands that they think are suicidal, and treat timetables as something flexible. This was the main British/American criticism of this summer's offensive. That the Ukrainians failed to do, what they had discussed with NATO planners - committing an overwhelming force on a narrow stretch of the front to effect a real breakthrough.
What you call Russian "meat waves", is actually a sign of strong discipline and morale. What you call Ukrainian ingenuity and improvisation, is actually a sign of poor command and control. Not always, but in this specific context - yes.
